  1. Go into the task definition
  2. Select the revision
  3. Click on action then deregister as in the given image
  4. make sure all revisions are deregistered
  5. You can see the Task definition is vanished from the list

Feb 2023: Announcing Amazon ECS Task Definition Deletion

The DeleteTaskDefinitions API closes the issue noted in the accepted answer. As previously, deregistering a task definition sets it as inactive. The new API allows you to delete INACTIVE task definitions:

aws ecs delete-task-definitions --task-definitions family:revision

aws ecs delete-task-definitions --task-definitions myInactiveTaskDef:1 myInactiveTaskDef:2 myInactiveTaskDef:3

There is no option to delete a task definition on the AWS console.

But, you can deregister (delete) a task definition by executing the following command number of revisions that you have:

aws ecs deregister-task-definition --task-definition task_defination_name:revision_no

It's a known issue. Once you de-register a Task Definition it goes into INACTIVE state and clutters up the ECS Console.

If you want to vote for it to be fixed, there is an issue on Github. Simply give it a thumbs up, and it will raise the priority of the request.

Created following gist to safely review, filter and deregister AWS task-definitions and revisions in bulk (max 100 at a time) using JS CLI.

https://gist.github.com/shivam-nagar/aa79b02b74f616f8714d51e419bd10de

Can use this to deregister all revisions for task-definition. This will result in task-definition itself marked as inactive.

Oneline approach inspired by Anna A reply:

aws ecs list-task-definitions --region eu-central-1 \
  | jq -M -r '.taskDefinitionArns | .[]' \
  | xargs -I {} aws ecs deregister-task-definition \
        --region eu-central-1 \
        --task-definition {} \
  | jq -r '.taskDefinition.taskDefinitionArn'

I've recently found this gist (thanks a lot to the creator for sharing!) which will deregister all task definitions for your specific region - maybe you can adapt it to skip some which you want to keep: https://gist.github.com/jen20/e1c25426cc0a4a9b53cbb3560a3f02d1

You need to have jq to run it: brew install jq

I "hard-coded" my region, for me it's eu-central-1, so be sure to adapt it for your use-case:

#!/usr/bin/env bash
get_task_definition_arns() {
    aws ecs list-task-definitions --region eu-central-1 \
        | jq -M -r '.taskDefinitionArns | .[]'
}

delete_task_definition() {
    local arn=$1

    aws ecs deregister-task-definition \
        --region eu-central-1 \
        --task-definition "${arn}" > /dev/null
}

for arn in $(get_task_definition_arns)
do
    echo "Deregistering ${arn}..."
    delete_task_definition "${arn}"
done

Then when I run it, it starts removing them: Deregistering arn:aws:ecs:REGION:YOUR_ACCOUNT_ID:task-definition/NAME:REVISION...
